(12). FDD1 Connector
A red mark on a wire typically designates the location of pin 1. You need to align the wire pin 1 to the
FDD1 connector pin 1, then insert the wire connector into the FDD1 connector.
(13). IDE1, IDE2, IDE3 and IDE4 Connectors
This motherboard provides two IDE ports (IDE1 & IDE2) to connect up to four IDE devices in Ultra
DMA 133 mode by Ultra DMA 66 ribbon cables. Each cable has 40-pin 80-conductor and three
connectors, providing two hard drive connections with the motherboard. Connect the single end (blue
connector) at the longer length of ribbon cable to the IDE port on motherboard, and the other two ends
(gray and black connector) at the shorter length of the ribbon cable to the connectors on hard drives.
AT7-MAX2's built-in HighPoint HPT 374 chipset gives you the capability to support Ultra DMA 133. It
provides two IDE channels (IDE3 & IDE4) that also support Ultra DMA 133 specifications, and it allows
for four additional IDE devices in your computer system. Especially, if you want to connect two or four
HDDs to get RAID functions, it is very convenient for you to install the HDDs to IDE3 or IDE4. See the
Chapter 4 for detailed information about RAID settings.
AT7-MAX2
This 34-pin connector is called the "floppy disk
drive connector". You can connect a 360K, 5.25",
1.2M, 5.25", 720K, 3.5'', 1.44M, 3.5" or 2.88M,
3.5" floppy disk drive.
A floppy disk drive ribbon cable has 34 wires and
two connectors to provide the connection of two
floppy disk drives. After connecting the single end
to the FDD1, connect the two connectors on the
other end to the floppy disk drives. In general,
people only install one floppy disk drive on their
computer system.
Note
If you want to connect two hard drives together
through one IDE channel, you must configure the
second drive to Slave mode after the first Master
drive. Please refer to the HDD documentation for
jumper settings. The first drive connected to IDE1 is
usually referred to as "Primary Master", and the
second drive as "Primary Slave". The first drive
connected to IDE2 is referred to as "Secondary
Master" and the second drive as "Secondary
Slave".
Keep away from connecting one legacy slow speed
device, like CD-ROM, together with another hard
drive on the same IDE channel, this will decrease
your integral system performance.
